This inventionrelates to a device for suppor-ting a stenographersnotebook at the rear of a typewriter so that the operator canreadilyiollow and transcribe the notes on the leaves of the notebook. I

More particularly, the present invention relates to a device of theabove kind wherein manually operable vmeans is provided for elevatingthe leaves of the notebook-in a-step-by-step tashion so that the linesof notes may be most convenientl-y (followed as transcription proceeds,and

for turning the leaves as transcription of the lines of notes thereoniscompleted.

An important-object of thepresentinvention-is to provide a device of theabove kind in which the leaf elevating and turning means is-conveniently operable at a ,point remote ,from the notebook andadjacent t'hekeyboard of the typewriter,

so that use of the device entails a minimum loss of time and effort onthe .part of the operator of the typewriter.

Another object of the present invention is to provide an actuating meansfor the leaf elevating and turning device by means of which intermittentelevation of the leaves of the notebook may be conveniently effected forvariable distances in accordance with the variable line spacing of notesas commonly taken on" a stenographer s notebook.

A further object is to provide a device of the above kind which willefiectively accommodate notebooks of various widths and lengths.

Still another object of the invention is to provide a device of theabove kind which is com,- paratively simple and-compact in construction,highly efficient in use, andotherwise well adapted to meet with therequirements'for a successful commercial use.

ing the nuts M; The 11917650012 is adfiptd'to supported on th rest III,II by placing the book so that it is preferably hung over the upper edgeof the plate III, a shown by dotted lines in Figure 4, the front coverof the notebook being disposed at the back of the plate [0, and the rearcover of the notebook being disposed flatly against the front face ofthe plate It], together with the leaves on which the notes to betranscribed have been written. In order to hold the leaves of the bookeven and to accommodate books of various widths, spaced guide strips l5are provided on the front of the plate 10 near opposite side of thelatter and in position to engage the side edges of the leaves of thebook, said guide plates l5 being adjustable toward or away from eachother. For effecting the latter adjustment, the guide plates l5 haverearwardly projecting bolts l6 that extend through transverse elongatedslots I! in the plate l near the ends of said guide strips 1 5, nuts 13being threaded on the rear projecting ends of the bolts 16. Bytightening nuts IS, the guide strips I may be effectively secured inadjusted position. The plate I0 is further provided with a longitudinalelongated slot l9 intermediate the side edges thereof and in the lowerportion of the same. Adjustable in the slot [9 i a bolt 20 having a nut2| threaded on the forward projecting end thereof. By tightening the nut21, the bolt 20 may b secured in any vertically adjusted position, andwhen so tightened, the nut 2| forms an abutment for the lower end edgeof the rear cover of the notebook 50 that the latter is effectivelysustained against lowering at the front of the plate Ill. The verticaladjustment of bolt 20 and nut 2| provides for the accommodation ofnotebooks of varying lengths.

J ournaled in the upper portion of the frame 6, I, 8, directly beneaththe upper flange of the cross piec I, is a horizontal leaf elevating andturning roller 22 suitably constructed to have an effective frictionsurface and arranged to engage the front or foremost page of thenotebook near the top of said page or leaf. The cut-out or notch 9exposes the rear portion of roller 22 for effective engagement with theleaves of the notebook and provides clearance whereby the ends of theleaves may readily pass as they are elevated and turned rearwardly. Thisturning of the leaves is facilitated by means of an upwardly andrearwardly curved guide 23 mounted upon the cross piece I so as topositively direct the leaves rearwardly and prevent them from fallingforwardly over the cross piece I. By adjustably tilting the book rest,its leaves may b maintained in frictional engagement with the roller 22,the upper end of the book rest being adjustable toward or from saidroller 22. Further, in order to guard against upward slipping of thenotebook at the front of the plate [0, the latter is preferably providednear its upper end with forwardly projecting inclined pins 24 arrangedtopenetrate the rear cover of the notebook and thereby aid in securingit against shifting relative to the plate I0. It will be apparent thatby rotating the roller 22 in an anti-clockwise direction as viewed inFigure 4, the front leaf of the notebook may be elevated in astep-by-step fashion for any required distance to accord with the linespacing of the lines of notes on the notebook. Also, the line being readmay be maintained directly below the roller 22 so that th latter willact as a guide to facilitate reading of the line. When the last line onthe page has been transcribed, rotation of roller 22 will effectcompletion of elevation of the leaf and rearward turning thereof so thatthe next page of the notebook is exposed for use.

Thus far described, the construction of all illustrated forms of theinvention is similar, and like elements of all forms are indicated bysimilar reference characters.

' The invention also provides manually operable means for turning theroller 22 so as to cause the step-by-step elevation of the leaves of thenotebook and turning of such leaves. Such means for rotating roller 22is operable at a point remote from said roller 22 and adjacent one sideof the keyboard of the typewriter disposed on the base 5. In theembodiment of Figures 1 to 5, inclusive, the operating means for roller22 consists of a flexible shaft 25 coupled at one end to an end of theshaft of roller 22 and extending through a tubular housing 26 which isalso flexible. One end of tubular housing 26 is coupled at 21 to theadjacent frame member 6, the other end of housing 26 being fixed at 28(see Fig. 5) in an opening of a vertical plate 29 secured to the rearface of the vertical flange of an angle bracket 30 whose lowerhorizontal flange is secured at 3| upon the forward portion of baseplate 5 near one side of the latter. A spindle 32 is journaled in anopening 33 of the bracket 30 near its rear end, and said spindle isprovided at its rear end with an enlarged circular head 34 rotatable ina circular recess 35 provided in the front face of the plate 29. Thespindle 32 is secured on the adjacent projecting end of flexible shaft25, and it will be apparent that it is journaled and held in position bythe plate 29 and bracket 30. The forward end of spindle 32 is providedwith a knurled knob 36 to facilitate manual turning of shaft 25 wheneverthis means is desired to be used for effecting rotation of roller 22.However, means is Drovided'for effecting step-by-step rotation of shaft25 and similar rotation of roller 22 by reason thereof. For thispurpose, a finger lever 31 is pivoted at one end upon the spindle 32behind a ratchet wheel 38 secured on said spindle 32, the lever 31 andratchet wheel 38 being mounted between the knob 36 and the bracket 30.Pivoted on lever 31 is a spring-pressed pawl 39 arranged to engage theteeth of ratchet wheel 38, and lever 31 is normally yieldingly elevatedby means of a helical tension spring 40. It will thus be seen that upondepression of the finger lever 31 against the action of spring 40, pawl39 will engage the teeth of ratchet wheel 38 and effect partial rotationthereof so as to correspondingly turn the shaft 25 and roller 22. Thisprovides a means of variable line spacing in that it may be used toelevate the leaf of the notebook any desired distance, depending uponthe stroke of the lever 31. As soon as the lever 31 is released, spring40 returns it to elevated position and positions the pawl 39 for thenext stroke. In order to properly limit the return stroke of pawl 39,acam lug is provided at II on the front face of the bracket 30 and in thepath of said pawl so that said pawl will be automatically disengagedfrom the teeth of ratchet wheel 33 when it has reached its limit ofreturn movement under the influence of spring 40. Accidental retrogradeturning of ratchet wheel 38 and shaft 25 is prevented by a suitablespring detent 42 mounted on bracket 30 and engaging the teeth of ratchetwheel 38. As the lever 31 is located at one side of the typewriterkeyboard, it can be conveniently and quickly reached and operated so asto "fiect turning-6f tl'ie roller 22 with a' m inimum"lessortimeand"expenditure of effort. In tials Embodiment, "it has been'found that a SIig-Iit amount of 'lo'st m'otion Will-behad "due 'to theuse of the flexible shaft 15, and this lost motion would ordinarilypermit creeping or slight retrograde 5 turning of 'roller 22 after beingactuated. As thiswould allow slightobj ectionabl'e shifting of "thenotebook-leaf after being elevated -to the desired degree, it isprevented by -means of a "spring preSsed detent *43 'mounted "on a framemember B and engaging the teeth "of a ratchet -wheel 44 fixed on "theshaft of roller 22 at "one end of the latter.

In" the [embodiment of Figures -6 to* 8,'-"inc1u- "sivef'the shaft ofroller 22has a "bevel gear: 45

"noted "o'non'e 'end thereof and 'me'shing 'with' an- I other gear 46"fixed on the upperend er sin '11 journaled at one side of the frame 6,138,

in brackets "48 "secured "to the adjacent -f'rame "memberifi. Thelowerend of the shaft-Mis re- "ceived in a thrust bearing -49 'mountedon *the base plate ""5, and a further-gear "50 is-secured onthe'iowerportion of shaft 41 and meshes with another gear "5! fixed onthe'rear-en'd or a hori- "zo'ntal forwardly extending operating-shaftfl"journaled adjacent but above 'thebase plate 5 "along one side 'of'thelatter. The'fo'rward 'n'd of"shaft52' isjournaled in andprojects-forward- "1'y"through "an anglebracket "53 secured on baseplate "'5, and the forward terminal of shaft "52 has a"knob"54'securedthereon. Pivotedat one end on' the shaft 52, between the knob/ 54 andb'racket 53 is afinge'r lever'55 having'a'spring- .jpressed "pawl '56hinged thereto and "arranged "to engage the teeth'of' a ratchet'wheel 51secured on .fshaft 52 between lever'55 'and bracket 53. FA helicaltension Spring '58 acts to swing 'the finger lever-'55 in one directionso as to'position pawl 56 for engagement with theteeth of ratchet wheel'51 on the next operative "strokeof the hnger 1ever55, the returnmovementof the'jpawl "56 resulting in its engagement with a 'cam lug 59by means of which it is disengaged from the "teeth of ratchet'wheel 151so as to 'limit"thereturn strokeof said lever. Accidental'retrogra'deturning ofshaft 52 and ratchet "wheel 5'! is'prevented by means of aspring detent'fifl 'fi'xed'onthe 'bracket' 53'and engaging the teethoi'iratchet wheel51. It will be seen that upon swinging the 'lever'55'to the. right in' 'FigureB, the shaft SZ'may -be partially rotated for'similarly'turning roller int-and efiecting the step-by-step elevationof 'thenotebook leaf. Also, spring58acts tore:

turn thellever and its pawl to the position'for thenextstroke. of lever55. Lever'55 islocated beside the keyboard of the typewriter whenthelatter is placed on the base plate 5 so that step- -by-step rotation ofroller 22 may be conveniently effected with a minimum expenditure oftime and effort. At the same time, when a great devgreetoffielevation ofthe notebook page is de- --sire'd,-knob 54 may be utilized. By this useof rigid shafts and. gears, use ofthe detent 43 and ratchet wheel .44.of Figure 1 is not necessary.

"In the embodiment of Figures 9 and'IO, a'projecting end of the shaft ofroller '22 has, a ratchet wheel 6i secured thereon, and "pivoted on saidshaft inwardly of the ratchet wheelfil is one end fa lever 62 having apawl 63 pivoted'thereto and arranged to engage the teeth ofithe ratchet-tvheeF'Bl.
